R help - Feb 2009 - Source code for nlm()

Hi,
 
Where can I find the source code for nlm()?  I dowloaded the R2.8.1.tar.gz
file and looked at all the .c and .f files, but couldn't find either nlm.c
or nlm.f
 
There is an nlm.r file, but that is not useful.
 
Thanks for any help,
Ravi.

It seems to be in optimize.c

Rgonzui has a very nice search facility for source of R or CRAN packages
(however it is against R 2.8.0 source):

I don't see why you say it's not useful, because it's the starting
point
to find the code.

See

  Ligges, U. (2006): R Help Desk: Accessing the Sources. R News 6 (4), 
43-45. http://cran.r-project.org/doc/Rnews/

for the next steps.  (To save you some time:  look in 
src/main/optimize.c.  But Uwe's article would have got you there pretty 
quickly).
